(Note: This document was originally written as a background paper for
the Women's Working Group of IPEN ( International Persistent Organic Pollutants
Elimination Network.) IPEN is the NGO network organized to participate in current UN
negotiations about chemicals classified as Persistent Organic Pollutants. The United
Nations is currently considering the elimination or reduction of twelve of some of the
most damaging chemicals that are Persistent Organic Polutants (POPs) through the
formulation of an international, legally binding treaty. Nine of the POPs chemicals under
consideration are pesticides that have been extensively used in both developed and
developing countries. Although many countries have banned these chemicals, they remain
stockpiled, are produced or used illegally, or, because of lenghthy half-lives, they
continue to exist in soil, or other environmental media. In Geneva, this paper instructed
both government delegates and public interest groups about how these chemicals are
particularly injurious to women's bodies.)
This document contains a description of human reproductive health problems connected with
chemical pollution and in particular pollution from POPs in the European region and
recommendations for an effective program for POPs elimination.

GENERAL INFORMATION ABOUT POPs AND THEIR IMPACT ON REPRODUCTIVE HEALTH
INTRODUCTION.
Reproductive health is now part of the official language and its policies and programs.
When we say 'reproductive health', we mean the ability of healthy women to bear healthy
children with healthy men. Reproductive health also refers to the ability of these healthy
children to develop into healthy adults and then to bear healthy children themselves. It
means that if we speak about 'reproductive health', we speak not only about women's
reproductive systems but also about health of men and children. And reproductive health is
probably one of the most important health aspects to care about, - only with an adequate
reproductive health policy can humanity have a future.
The problem of reproductive health is of great and growing concern. Environmental
factors which cause the greatest damage to reproductive health are the result of the
development of industrial technologies which exist only since a few years or decades.
Among these environmental factors are toxic chemicals. That is why the highest rates of
breast cancer are found in industrialised countries. The WHO predicts that the number of
cancer deaths will double in most countries over the next 25 years. Also contamination
from most environmental pollutants is the highest in developed countries. Yet breast
cancer is rising very fast in developing countries (about 4% per year), while in developed
countries it increases by 1% per year. A breastfeeding infant in the U.S. or other
industrialised countries may consume an average of 35-53 pg Teq/kg/day of dioxins in its
first year of life (the current U.S. Environmental Protection Authority virtually safe
dose is 0,006 pg TCDD/kg/day). This is many times higher than for an infant in a
non-industrialised country.
There is another important aspect of the problem. That women's health can be used as
indicator of the state of the environment, is a perspective not often taken. But
increasingly well-documented evidence support the fact that women (and consequently
children) are the first to experience the effects of environmental degradation.
Many factors can cause damage to reproductive health, but one of the most important are
chemicals and among chemicals - POPs, Persistent Organic Pollutants.
CHEMICALS IN ENVIRONMENT.
… More than 100,000 chemicals have entered into the market since 1945, and it is
estimated that 75,000 of them are still in commercial use. Most of these chemicals remain
untested for their safety in humans and other species.
… 44% of 50 countries surveyed by WEDO (Women's Environment & Development
Organisation) all over the world (1999) report reproductive health disorders as a result
of chemical exposure in the work place and other occupational hazards.
… The health effects of water pollution are especially severe on women and
children. In the Ukraine, 13 % of the illnesses affecting women and children have been
linked to water pollution, and 21 % to air pollution.
… In Russia pollution has led to doubling of bladder and kidneys disorders in
pregnant women. In the Ural region, the synergistic impact of a cocktail of chemicals is
causing birth defects, tumours, malignant blood diseases and diabetes.
… In Uzbekistan, prolonged use of water polluted by pesticides and industry has
led to increases in pregnancy complications and birth defects, and a higher incidence of
anaemia, and kidney and liver diseases in women.
… In the U.K. government experts found that 12,000 to 24,000 people might die
prematurely as a result of exposure to air pollution. The incidence of breast cancer here
has risen massively, and is now one of the highest in the world. 1 in 12 women risk
contracting breast cancer in their lifetime, and there is evidence that this rate
increases to 1 in 11 in certain regions of the country. Also, women in certain occupations
are at higher risk of contracting the disease.
… In the developed world, there is a dramatic increase in asthma. Often thought to
be a disease of childhood, asthma has a clear impact on millions of adults, women in
particular. In the U.S., for example, death rates from asthma are 59 percent for women and
only 34 percent for men.
… In the U.S. and other industrialised countries, exposure to dioxin in adults is
near levels at which WHO warns that subtle adverse neurological and endocrine effects may
already be occurring. In the U.S population of 260 million for example, a range of 111 to
1,114 cases of cancer may be directly linked to dioxin exposure from the food chain.
(These data are from WEDO's report "Risks, Rights and Reforms", New York 1999).
… The U.S Environmental Protection Agency has formally recognised that health
effects associated with hazardous waste sites include birth defects cardiac disorders,
changes in pulmonary functions, impact on the immune system, infertility and increases in
chronic lymphocytic leukaemia. A Europe-wide study published by the European Commission
found that women whose foetuses were malformed were more likely to have lived close to
landfills than those whose babies were normal. In February 1999, the Philippines became
the first country in the world to impose the nation-wide ban on incinerators, because they
can spew extremely harmful pollutants into the atmosphere, even those with modern
technology.
PERSISTENT ORGANIC POLLUTANTS
(POPs).
POPs are toxic, persistent and bio-accumulative substances of organic (carbon-based)
chemical compounds and mixtures. These chemicals are products and by-products of human
industrial activity that are relatively recent in origin. In the early decades of this
century, pollutants with these harmful properties were virtually non-existent in the
environment and food. Now this group includes a large number of pesticides, industrial
chemicals (polychlorinated biphenyls - PCBs, hexaclorobenzene) and unintentional
by-products (dioxins, furans).
POPs are persistent in the environment, some of them can be found in the environment
after decades and even centuries. They are also subject to global distillation (i.e.,
migration from warmer to colder regions).
Surveys over three decades in many parts of the world have shown that DDT (or its
breakdown product DDE) as well as most other POPs are found in food products in most
regions of the world, especially in fish, meat and dairy products. Because they generally
have low water solubility and high lipid (fat) solubility, POPs tend to accumulate in
fatty tissues of living organisms.
POPs presently being negotiated in the UN to be eliminated

PART II
POPs AND REPRODUCTIVE HEALTH
POPs and human health
POPs are highly toxic, and have the potential to injure human health and the
environment at very low concentrations, sometimes at the concentration of only one or a
few molecules.
Damage caused to humans and other species by POPs is well documented and includes:
… the pathologies of cancer and tumours at multiple sites; … reproductive
disorders; … neurobehavioral impairment including learning disorders; … immune
system dysfunction; … lack of development in various body system such as the
reproductive system, endocrine system, immune system and neurological system; …
adverse effects to the adrenal glands, the liver and the kidneys; … heart diseases;
… cerebro-vascular diseases; … still births; … behavioural changes such as
fatigue, depression, personality changes, tremors, convulsions. … respiratory
diseases.
Hormone Disrupters
Of the 51 synthetic chemicals that have now been identified as hormone disrupters, at
least half, including PCBs, are "persistent" products and in that way resist
natural processes of decay that render them harmless. These long-lived chemicals will be a
legacy and a continuing hazard to the unborn for years, decades, or in the case of some
PCB's, several centuries.
In half a century of production, however, the synthetic chemical industry world wide
(excluding the USSR) had produced an estimated 3,4 billion pounds of PCBs, and much of it
was already loose in the environment and beyond recall. Moreover, the ban put on
production of PCB's in the US and other industrialised countries in the seventies, did not
address existing PCBs, allowing their use to continue in closed applications - such as
transistors, electric ballast, and small appliances - even today.
Hormones and prenatal development. The hormones estrogen and testosterone are the
body's sexual messengers ordering embryo's how to grow. Without these testosterone
signals, male development gets derailed and boys don't become boys. Instead they become
stranded in an ambiguous state, there they cannot function as either males of females. In
scientific terms, these are "intersex" individuals or hermaphrodites - a term
that comes from the Greek deity Hermaphrodite whom classical sculptors portrayed as a
figure with male genitals and female breasts (Theo Colborn, Dianne Dumanoski, John
Peterson Myers. "Our Stolen Future", New York, 1996.)
Even a minuscule dose of hormone during the onset of animal embryo's sexual
development, can trigger abnormalities in sexual behaviour, and may cause malformed
genitalia, lowered sperm count.
Because hormones also regulate the embryo's immune system and brain development the
offspring might be prone to disease and behavioural disorders.
Hormone mimics. To date, researchers have identified at least 51 synthetic chemicals -
many of them ubiquitous in the environment - that disrupt the endocrine system in one way
or another. Some mimic oestrogen like DES (Diethylstilbestrol) , but others interfere with
other parts of the system, such as testosterone and thyroid metabolism. This tally of
hormone disrupters includes large chemical families such as the 209 compounds classified
as the PCBs, the 75 dioxins, and the 135 furans, which have a myriad of documented
disruptive effects. (Theo Colborn, Dianne Dumanoski, John Peterson Myers. "Our Stolen
Future", New York, 1996.)
Gray and his colleague William Kelce have also recently discovered that DDE, an
ubiquitous chemical and the DDT breakdown product found most often in the human body, acts
as an androgen blocker. Like vinclozolin, it binds to and blocks the androgen receptor, so
the body's own signals do not get through. Gray believes there are more anti-androgens to
be discovered and more out in the environment than anyone has suspected.
Other hormone disrupting mechanisms. However important, oestrogen and the receptor
mechanism are far from the hole story on endocrine disruption. Man-made chemicals scramble
all sorts of hormone messages, and they can disrupt this communication system without ever
binding with a receptor. If cellular phone messages aren't getting through, the problem
isn't necessarily with your phone. There may be trouble somewhere else in the system, such
as in the satellite that relays the message from continent to continent or the transmitter
that sends the message into space. The same holds true for the endocrine system (example
taken from "Our Stolen Future", Theo Colborn e.a.).
An oestrogen mimic may interfere with our hormone regulation in different ways e.g. it
may block the pathway so the natural hormone may not reach its receptor site; it may
pretend to be a hormone and initiate an abnormal response; it may fit into the receptor
site and block the hormone pathway or it may interfere with the metabolism of hormones or
their transport in the body. It may also push the body down the pathway of producing too
much 16aOHE which is undesirable in terms of breast cancer, whereas a higher ratio of
2-OHE (2-Hydroxysteron, one of the oestrogen hormones) is likely to be more beneficial and
possibly protective. A large number of chemicals are oestrogen mimics - at least 52 have
been identified as interfering with our endocrine system and many of those are also
carcinogenic. (Oestrogen Mimics. Putting Breast cancer on the Map, The Women's
Environmental Network, London, 1999)
"Endocrine disrupting chemicals have been reported in semen, the ovarian follicle,
the womb environment, and in breast milk at especially elevated concentrations of actions
and unique target sites" (Theo Colborn; Environmental Health perspectives, Oct.
1995).
Certain chemicals can pass through the placenta from mother to developing foetus. Since
the foetus is exquisitely sensitive to even minute quantities of HDCs, it has been
suggested that the chemicals we are exposed to in the womb may have an effect years later.
For example a synthetic oestrogen, Diethylstilbestrol (DES) was given to over five million
women from 1948-1971 and is regarded today as a "model for the problems that other
oestrogen-like substances may cause".(Sue Dibb "Swimming in a Sea of
Oestrogens", The ecologist, No1, Febr.1995). Originally prescribed to prevent
miscarriage, DES was also used for menopausal symptoms , as a "morning after"
contraceptive, for girls who were growing "too tall" and most bizarre of all, by
farmers to fatten chickens, cows and other livestock. Years later daughters and sons of
women who took the drug developed various cancers and genital abnormalities. (Oestrogen
Mimics. Putting Breast cancer on the Map, The Women's Environmental Network, London, 1999)
The greatest damage can occur during pregnancy, when some POPs mimic or block the
miraculously delicate signals that the mother's and foetus' hormonal system sends to the
developing foetus to guide its development. According to some recent scientific studies by
Colborn (1996), De Vito (1995), Jacobson and the EPA (1994), as the child develops,
endocrine disruption in the womb and through breast milk may result in cancer,
endometriosis, learning disorders, immune and neurological disorders and a wide range of
other problematic conditions such as low sperm count and sperm volume decline,
miscarriages, low IQ, genital malformations and infertility.
POPs' injuring women's health
and reproduction.
POPs have been associated with particular impacts on women which affect their ability
to bear healthy children, capable of developing into healthy adults. The following
pathologies have to be taken into account relating ffoetal contamination and women's
ability to bear healthy children:
Miscarriage. Animal studies indicate that exposure to certain synthetic chemicals, such
as PCBs, increase the risk of miscarriage. Similar studies implicate chemical exposure
with ex- uteri pregnancy.
Intellectual Development. Studies done by Sarah and Joseph Jacobson on the intellectual
impairment of children exposed intrauterine to PCBs indicate that these children suffer
from lower full-scale and verbal IQ scores, with strongest effects being reported on
memory and attention. What is of concern is that these effects are seen in children
exposed to PCB concentration only slightly higher than those found in the general
population.
Sperm Count. Shocking findings have been announced in the last few years in regard to
infertility of men. A literature review revealed that there has been a serious decline in
both volume of semen and the number of sperm between 1949 and 1990. In the research
(Carlsen, E et al, "Evidence for the decreasing quality of semen during the past 50
years", British Medical Journal, Vol. 305, 1992, pp. 609-612) which reviewed 61
papers from 61 countries showed that semen volume declined from 3,40 to 2,75 ml and the
number of sperm from 113,000,000 to 66,000,000 per ml. Accumulating evidence suggest that
'estrogens' could be responsible for disturbing maturation of males that may seriously
affect male fertility.
Immune System Dysfunction and Immunodeficiency Syndrome. Recent studies indicate that
children in the high Arctic do not produce the necessary antibodies when they receive
vaccination for smallpox, measles, polio and other diseases. Babies in the Arctic take in
seven times more PCBs than other infants which can been suggested to be linked to the fact
that people eat wild meat and fish and that therefore breast milk is highly contaminated.
Also in Europe on background exposure signs of immunotoxicity are detected (Prof. Janna G.
Koppe)
Temperament Change. Darvill and others have studied children born to mothers who ate
contaminated fish from Lake Ontario. These fish were contaminated with a wide range of
POPs like PCBs, dioxin, dieldrin, chlordane and mirex. The children appear to be
over-reactive to stimulation, demonstrate a greater number of abnormal reflexes, and do
not smile or seem to experience joy as much as do children whose mothers did not eat
contaminated fish.
There are also a number of very serious diseases which have direct relation with POPs
in the environment.
1. Breast Cancer
A series of studies have analysed the linkages between several POPs and breast cancer.
POPs are detectable in almost all samples of adipose tissue or the fat of human breast
milk. Eleven studies have analysed various organochlorine compounds including DDE, PCBs
and other pesticides and breast cancer. These include studies by Frank Falck, Mary Wolff
and others who compared blood samples of women with breast cancer and found that DDE (a
metabolite of DDT) levels were 35% higher in women with cancer.
Breast Cancer Facts from the U.S.
(WEDO)
… Breast cancer now strikes one in eight women in North America. Almost one third
of those will die of it. … In 1950 in the U.S., the incidence of breast cancer was
one in twenty. From 1980 to 1987, the rate of breast cancer incidence increased by 32%.
Since 1950, it has increased by 57%. … Breast cancer is a leading cause of cancer
death for black women aged 15-54 in the U.S. … The incidence rates of pre-menopausal
breast cancer are higher in black women than in white women, and the reverse is true for
post-menopausal cancer in the U.S. … Seven out of every ten U.S. women that develop
breast cancer have no known risk factors (such as: age, delayed or reduced childbearing,
family history, early onset of menstruation). … Studies of immigrant populations have
found that when women migrate to the U.S. from countries that experience significantly
lower breast cancer rates, their incidence rates rise to U.S. levels.
The environmental Connection.
There is growing body of scientific evidence suggesting a link between breast cancer
increase and avoidable environmental contaminants: … Scientists believe a ban on
three carcinogenic pesticides may be responsible for 30% drop in breast cancer rates in
Israel in 1976-1986 despite a worsening of known factors. … Levels of PCBs and DDT
were reported to be 50-60% higher in the breast tissues of women with breast cancer than
in women without breast cancer in a study in Connecticut.
Lactation and the breastfeeding problem. Studies by Walter Organ, Caren Lanting and
others show that the presence of DDT and PCBs in breast milk can reduce the ability to
breast feed, with a 40% decrease in lactation time reported among women with the highest
levels of DDT and PCBs in their breast milk.
22% of 50 countries, surveyed by WEDO world-wide , report breast milk contamination
from chemical exposure.
Breast milk contamination
Breast is toxic?...
The problem of breast milk contamination and breastfeeding has been a major subject of
debate. Since the early 1980s, when high levels of PCBs were detected in breast milk in a
number of European countries, the question was raised whether it was still advisable to
feed new-born babies on breast milk, especially when formula milk was available.
... but breast is best!.
The main conclusion of numerous researches is that: Despite the fact that breast milk
can be a major source of PCBs and dioxins, it also provides essential elements for optimal
child development, for activating of the immune system, which are not present in formula
milk (for example, antibodies against some infection diseases).
The research of Dutch scientists (1989, 1993) showed that even when plasma sampled from
breast-fed 42-month-olds contained 4,5 times as much PCBs as plasma obtained from children
who had been formula-fed as babies, exposure to PCBs and dioxins via breast milk was
unrelated to brain development at 42 months of age. All in all, despite the presence of
PCBs and dioxins in human milk, breast-feeding has a small advantageous effect on
long-term neurological development. (Caren I. Lanting, 1999)
Despite the presence of PCBs and dioxins in human milk, breast-feeding should be
advocated.
However, all possible measures should be taken to reduce the level of dangerous
chemicals (and further - to eliminate them) in breast-milk, (see recommendations).
Benefits of breastfeeding. … Breast milk is the ultimate in nutritious fast food;
always ready to serve at the right temperature and in clean conditions. But more than a
meal and drink, breastfeeding strengthens resistance to infection and protects against any
infections the mother is exposed to.
… Bottle fed infants are much more susceptible to gastric and respiratory illness
than breastfed babies even in the most sanitary conditions in an industrial nation like
Britain.
… Breast feeding is also associated with a reduced risk of Sudden Infant Death,
respiratory infections, eczema, diabetes, and with increased intelligence and better
nervous system development compared to bottle fed babies.
… It appears that it is the baby suckling which determines hormone levels in the
mother which in turn determine the return of ovulation. Breastfeeding thus has a
contraceptive effect.
… Other maternal benefits are protection against pre-menopausal breast cancer,
ovarian cancer, and hip fractures in old age.
2. Endometriosis
Statistics on the incidence of this disease world wide is still lacking. But
endometriosis appears to be on the rise in the US, where it afflicts 10-20% of women of
childbearing age. Prior to 1921, there were only 20 reports of the disease in world wide
medical literature. German researchers report that women with endometriosis have higher
levels of PCBs in their blood than women who do not suffer from this disease. Animal
studies indicate that endometriosis is closely linked with exposure to dioxin. . (WEDO,
Greenpeace, 1998).
Endometriosis is a puzzling disease affecting girls and women in their productive
years. The name comes from the word "endometrium", which is the tissue that
lines the inside of the uterus and builds up and sheds each month in the menstrual cycle.
In endometriosis, tissue like endometrium is found outside of the uterus, in other areas
of the body. In these locations outside of the uterus, the endometrial tissue develops
into what are called "nodules", "tumors", "lesions",
"implants", or "growths". These growths can cause pain, infertility,
and other problems.
Recent research has indicated women and girls with endometriosis are at greater risk of
cancer, particularly ovarian and breast cancer, as well as non-Hodkin's lymphoma.
The cause of endometriosis is not known, but a number of theories have been advanced.
One of them is the retrograde menstruation or transtubal migration theory. Another theory
suggests that the endometrial tissue is distributed from the uterus to other parts of the
body through the lymph or blood. A genetic theory suggests that certain families may have
predisposing factors to endometriosis.
Recent research spearheaded by the Association of Endometriosis has shown that
environmental toxins such as dioxins and PCBs, which act like hormones in the body and
damage the immune system, cause endometriosis in animals (Endometriosis Association,
1999).
PART III
RECOMMENDATIONS
Women participating in the IPEN conference of NGOs, 4 and 5 September 1999 in Geneva,
are calling on Governments to give the highest priority to elimination of POPs because of
the dangers these substances pose to the most vulnerable aspects of human health: the
reproductive system and the mental and physical development of children from prenatal
phase through puberty .
From the research results and testimonies presented by women from different parts of
the world at the IPEN conference, it becomes clear that exposure to POPs can have an
impact on the ability of prospective parents to conceive, on the ability of mothers for
safe breastfeeding and on the intellectual, behavioural and physical development of the
child. Persistent Chlorinated Compounds, which act as hormone disrupters, can accumulate
in the body and exert their effects as they are released into the system during pregnancy.
The policy on POPs has to be strengthened taking the above aspects fully into account.
Therefore we call upon governments:
… To phase out the production as well as the use of POPs. An elimination of the
POPs at the source should be implemented immediately. This elimination should first focus
on the twelve priority POPs, including DDT, PCBs and dioxins for which a convention is in
the process of being negotiated. There must be developed criteria and procedures based on
environment health protection to identify new POPs for elimination, … To apply the
precautionary principle: no chemical should be allowed on the market before sufficient
scientific proof exists that the chemical is not dangerous to human health, not only in
short-term but also in long-term use. … To promote more research to identify POPs in
human tissues and to analyse the links between human health and POPs in environment.
… To promote research to clean the body of POPs, so that the offspring is no longer
intoxicated by POPs in the prenatal phase and by breastfeeding. … To recognise that
breastmilk- being according to numerous research the best nutrition for the optimal
development of every child - has to be free from POPs. … To provide the systematic
control on food production and consumption to identify the harmful chemicals and fully
protect the consumers. … To develop labelling schemes for products and goods
containing POPs, so that consumers can take informed decisions. … To replace
chlorinating of water by safer and effective methods (for example, ozone , ultraviolet
light ) … To enable a POPs-free approach in the control of malaria and other
transmissive diseases. … To prohibit the use of POPs in public health care and
veterinary treatment, e.g. the use of lindane as a treatment for lice and scabies in
humans and against ectoparasites in sheep. … To develop and implement National and
Local Environment and Health Action Plans (NEHAPs and LEHAPs) containing policies to
protect human reproductive health and child development from POPs. … To provide
governmental support for the monitoring and mapping of the environmental health situation
- particularly the impact of chemical pollution - by women's organisations and other NGOs
and local groups in co-operation with scientists and experts - the results should be taken
into account in national policymaking.

Annex 1
Some of the most well known hazardous organochlorine pesticides.
1. DDT (Hazards and Exposure Associated with DDT and Synthetic Pyrethroids Used for
Vector Control, WWF report, January 1999.)
For decades, DDT has played a major role in global efforts to combat malaria and other
vector-born diseases. It was employed with striking early success against malaria.
Nonetheless, malaria continues to be a global menace - approximately2,5 billion people in
over 90 countries are currently at risk of contracting the disease. It is a leading cause
of illness and death in the developing world, contributing to approximately 3 million
deaths and up to 500 million acute clinical cases every year. Most deaths occur in
sub-Saharan Africa and over half are children under five years old - malaria kills four
children per minute or 5,000 per day.
Currently, DDT's only official use, as specified by World Health Organisation (WHO), is
for the control of disease vectors in indoor house spraying - although other (illegal)
uses are suspected.
It is manufactured in approximately half a dozen countries with global production
estimated in 1995 at about 30,000 metric tonnes per year.
Concentrations in humans of DDT and its breakdown product, DDE, are clear barometers of
exposure. Although DDT levels are decreasing in parts of the world, there are populations
of people and wildlife that experience concentrations of DDT and DDE above critical
levels. For instance, investigations in Mexico and South Africa reveal that human breast
milk contains DDE at concentrations that exceed the guidelines for the acceptable daily
intake by infants set by the WHO. Moreover, studies have shown that the length of
lactation (milk production) decreases with higher DDE body burdens in human mothers, thus
depriving infants of benefits provided by breast feeding.
In recent years , evidence has grown that elevated concentrations of DDE are associated
with reduced lactation by mothers. In many areas where DDT is still used, measured
concentrations exceeded health guidelines. Links exist between DDT and reproductive and
immunotoxic effects in wild life and humans due to the chemicals' disruption of sex
hormones and other chemical messenger systems in the organisms.
2. Lindane (from: A briefing for UNISON prepared by the Pesticides Trust, London, 1999)
Lindane - g-HCH [hexachlorocyclohexane], is included in the government "Red
List" of dangerous substances. It has been in use as an broad range insecticide for
50 years, long enough to build up a significant body of evidence on its toxic and
environmental hazards. It has caused deaths and poisonings in humans and there is
authoritative recognition of its long term health effects including carcinogenic effects.
It is a serious environmental contaminant and as well as being directly toxic to wildlife.
It bio-accumulates along food chains. Scientific and anecdotal evidence links lindane with
serious health problems including aplastic anaemia, the birth disorders C.H.A.R.G.E. and
breast cancer. (See below).
Lindane has been banned or severely restricted in 37 countries. The Advisory Committee
on Pesticides in the UK has so far carried out three reviews of lindane and continued to
recommend its approval. The Pesticides Trust believes that Lindane should be banned on the
basis of existing evidence and as a precaution to avoid further health and environmental
problems which are suspected of being caused by lindane.
Many other organochlorines which over the years have been linked to major health and
environmental problems have been banned or are no longer used. Included in this catalogue
are aldrin, dieldrin and endrin which have virtually disappeared, and DDT, heptachlor and
toxaphene which have been banned in many countries but are still used quite extensively
particularly in some developing countries. Lindane is an organochlorine insecticide that
is still in relatively widespread use in developed nations as well as in the third world.
It is still in use in treatment against lice and scabies in humans and also against
ectoparasites in veterinary treatment. In a control study, Davis et al. reported a
statistically significant increase of brain cancer in children following treatment with
lindane shampoo. ("Family Pesticide Use and Childhood Brain Cancer", 1993).
Veterinary use in sheep can cause contamination of wool, as well of milk and meat.
Lindane is also known as g-HCH since it has to be made up of at least 99% of the gamma
isomer of hexachlorocyclohexane (HCH). Technical HCH can include varying proportions of
alpha, beta, delta and epsilon HCH isomers, but because these have been shown to have
serious short and long term health effects, in the UK all HCH products containing less
than 99% of the gamma isomer are banned.
The organochlorines in general, and lindane in particular, are characterised by their
broad spectrum insecticidal activity, long persistence in the environment, and their
tendency to bio-accumulate along the food chain.
Several cases of human poisoning by lindane have been reported. Children are
significantly more susceptible to the toxic effects of lindane. In one case a dose
equivalent to 62,5 mg/kg proved fatal, while the LD50 in the rat is above 88mg/kg. In
adults, doses above 300 mg/kg ingested orally have proved fatal.
Since lindane has been in very widespread use for several decades, its long term health
effects have been extensively studied. Included among the reported chronic effects of
exposure to lindane are nervous disorders and increased liver weight.
The International Agency of Research on Cancer (IARC) has concluded that lindane is a
possible human carcinogen (class 2B), and the US EPA has classified it similarly as a
class B2/C possible human carcinogen.
Key health issues.
… Aplastic anaemia. Exposure to lindane has been linked with blood disorders known
as blood dyscrasias, and in particular the disorders aplastic anaemia where the formation
of platelets and white cells is disrupted. … C.H.A.R.G.E. This condition which
involves multiple congenital abnormalities has been linked to exposure of the mothers of
CHARGE children to lindane during early pregnancy. A statistically significant proportion
of mothers of CHARGE children in the UK were exposed to pesticides in early pregnancy, and
one of the most prominent pesticides implicated was lindane.(Blake and others, Child care
health and development, 1993, 19, 395-409) … Breast Cancer. Lindane is an endocrine
disruptor which is capable of imitating hormones in humans and thereby disrupting the
physiological functions which these hormones control. There is a significant body of
evidence which suggests that where lindane is used extensively, and particularly where
cattle are exposed to it, the incidence of breast cancer is higher. The UK has the highest
rate of death from breast cancer in the world, and in Lincolnshire were lindane is used
extensively on sugar beet crops, the rate of breast cancer is 40% higher than the national
average. (Women Environmental Network, 1994). The presence of lindane in human milk has
been reported in countries throughout the world (Moses, Marion, Pesticides and breast
cancer, Pesticides News 22, December 1993, 3-5).
Environmental effects. Lindane is highly volatile, and when applied to field crops in
particular, a high proportion (up to 90%0 of the pesticide enters the atmosphere and is
later deposited by rain. Lindane is also leached into surface waters and even into ground
water.
The International Conference on the Protection of the North Sea agreed to reduce
emissions from land, rivers and the atmosphere of number of toxic chemicals including
lindane by 50% between 1985 and 1995.
In common with other organochlorine pesticides lindane is fat soluble and this
contributes to its tendency to bio-accumulate through food chains. Residues have been
detected in the kidneys, liver and adipose tissue of a wide variety of wild animals and
birds. It is highly toxic to aquatic invertebrates and fish.
Annex 2
PCBs and Dioxins FROM "DIOXINS--THE VIEW FROM EUROPE" (RACHEL'S ENVIRONMENT
& HEALTH WEEKLY) AND CAREN LANTING "EFFECTS OF PRENATAL PCB AND DIOXIN EXPOSURE
AND EARLY FEEDING MODE ON CHILD DEVELOPMENT (GRONINGEN, 1998).
Introduced in 1929, PCB's became the first big commercial success for a new elite of
chemical engineers who would eventually synthesize tens of thousands of novel chemicals
that exist nowhere in nature. The engineers created PCBs by adding chlorine atoms to a
molecule with two joined hexagonal benzene rings known as a biphenyl. The result of their
tinkering was a family of 209 chemicals known collectively as polyclorinated biphenyls, or
PCBs, which soon proved to be immensely useful compounds.
In early assessments, PCBs seemed to have many virtues and no obvious faults. They are
non-flammable and extremely stable. Toxicity tests at the time did not identify any
hazardous effects. Confident of their safety as well as their utility, the Swan Chemical
Company, which would soon become a part of Monsanto Chemical Company in 1935, quickly
moved them into production and onto the market.
With the issuance of federal regulation requiring the use of nonflammable cooling
compounds in transformers used inside buildings, PCBs quickly found a steady major market
in the electrical industry. Other industries put PCBs to use as lubricants, hydraulic
fluids, cutting oils, and liquid seals. In time, these chemicals also found their way into
a host of consumer products and thus into the home. They made wood and plastics
nonflammable. They preserved and protected rubber. They made stucco weatherproof. They
became ingredients in paints, varnishes, inks, and pesticides. In retrospect, it is clear
that the very characteristics that made them a runaway commercial success also made them
one of our most serious environmental pollutants.
The term "dioxin" encompasses a family of 219 different toxic chemicals, all
with similar characteristics but different potencies.[1] This is the group of
polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). They have two
connected benzene rings. In the case of PCDDs, the benzene rings are connected by two
oxygen atoms, whereas in the PCDFs the benzene rings are connected by one oxygen atom.
Hydrogen atoms attached to the carbon atoms may by substituted with a chlorine atom.
Except as laboratory curiosities, dioxins are never intentionally produced because they
have no commercial value. They are unwanted by-products of thermal processes and of
chemical formulations. The following major categories of sources can be distinguished:
… Formation during incineration processes. This includes municipal waste combustion,
scrap metal recycling, vehicle fuel combustion, cigarette smoking and combustion of wood.
… Formation as by-products in industrial processes, such as in the production of
pesticides and in the pulp of paper industry. … Mobilisation of dioxins from
secondary sources, such as waste dumps and the application of sewage sludge as fertiliser.
For example, according to EPA, the major sources of dioxins in 1995 in USA were: …
municipal garbage incinerators (36% of the national total); … copper smelting ( 17%);
… medical waste incinerators (16%); … forest fires (7%); … cement kilns
burning hazardous waste ( 5%); … industrial coal combustion (2.4%); …
residential wood combustion (2%); … industrial wood combustion (1%); … diesel
engines (1%); … aluminium smelting (0.5%); … incineration of sewage sludge
(0.2%); Plus 12% of the national total spread directly into the nation's soils in sewage
sludge. (The total is not exactly 100% because of rounding.)
The predominant mode of environmental transport of PCBs and dioxins is the atmosphere.
They can be dispersed in the air either in vapour or in aerosol form especially during
inefficient incineration and during incineration of PCB-containing materials.
Subsequently, the more highly chlorinated PCBs and dioxins, which are virtually insoluble,
remain associated with the soil. The lower-chlorinated congeners have a small solubility
in water, where they probably cling to the sediment and are washed down-stream.
PCBs and dioxins in environment and humans.
Some evidence of toxic effects in workers began emerging as early as 1936, indicating
that PCBs were not as safe as previously believed. PCBs were on the market for 36 years
before serious questions surfaced publicly about this wonder chemical. In the meantime,
manufacturers kept coming up with new uses. From 1957 through 1971, paper companies put
PCBs in their carbonless copy paper, enabling typists, in an era before widespread use of
the copying machine, to make duplicates of documents without carbon paper.
The person to first recognise that PCBs had become a pervasive contaminant was the
Danish-born chemist S�ren Jensen. In 1964 Jensen, who worked at the Institute for
Analytical chemistry at the University of Stockholm, kept encountering mysterious chemical
compounds as he tried to measure DDT levels in human blood. Whatever it was, Jensen found
it wherever he looked - in wildlife specimens collected three decades earlier, in the
Swedish environment, in the surrounding seas, in hair samples of his wife and infant
daughter. The presence of the mystery contaminant in wildlife samples taken in 1935
indicated it could not be a chlorine-based pesticide, which came into broad use only after
World War II. It took Jensen more than two years of investigation to identify the
synthetic pollutant as PCBs. A report of Jensen's finding first appeared in the British
journal New Scientist in 1966.
As other scientists began to look for PCBs, they, too, found them everywhere - in soil,
air, water; in the mud of lakes, rivers, and estuaries; in the ocean; in fish, birds, and
other animals. Chemists had long puzzled about the elusive peaks that showed up repeatedly
on their gas chromatograph charts when they were analyzing samples taken from the
environment. The peaks which looked similar to those made by DDT, registered the presence
of some chemical, but until Jensen compared the peaks using a chemical sample provided by
German manufacturer, they did not know what the contaminant was. Finely, they had the
answer - PCBs.
Ten years later, in 1976, finally the United States banned the manufacture of PCBs, and
other industrial countries eventually followed.
In half of century of production, however, the synthetic chemical industry world wide
(excluding the USSR) had produced and estimated 3,4 billion pounds of PCBs, and much of it
was already loose in the environment and beyond recall. Moreover, the ban did not address
existing PCBs, allowing their use to continue in closed applications - such as
transistors, electric ballast, and small appliances - even today.
There is no way to discover exactly how the PCBs in the polar bears made their way to
the Svalbard archipelago or where they came from. But research over the past two decades
has given scientists a good understanding of how PCBs travel through ecosystems and
migrate over long distances.
Human population have been exposed to PCBs and dioxins via three major pathways: …
accidental; … occupational; … environmental.
As compared to the latter category, levels of exposure in the first two groups are
significantly higher. PCBs and dioxins can be found in all compartments of the human body,
including adipose tissue and blood lipids. They pass the placenta, and they are
transferred into human breast milk fat .
Accidental exposure to PCBs and dioxins.
Three general populations, that have accidentally been poisoned with PCDDs and PCDfs
exist.
The first incident took place in 1968 in Japan which 1770 persons were affected. This
incident was called 'Yusho'. In that case cooking oil was contaminated with a complex
mixture of PCBs, dibenzofurans, and quaterphenyls.
A similar incident occurred in Taiwan in 1979, with more than 200 victims. This one was
called 'Yu-cheng'(oil disease). The clinical manifestation of chronic poisoning consisted
of acne form eruptions, hyperpigmentation, peripheral neuropathy, abdominal pain and,
deformation of the nails. Because chemicals persist in human tissue, and because they pass
the placenta the offspring of female patients was exposed in utero. The exposed children
tended to have a low birth weight and more frequently showed dystrophic fingernails and
pigmented or dystrophic toe nails than the control group. These babies also had an
increased rate of hyperpigmentation and acne, and a higher rate of generalised itching,
localised skin infections and hair loss. In addition, neonatal conjuctival hypersecretion
and jaundice occurred more frequently. At follow-up, the exposed children showed a delay
in growth, cognitive and motor development.
Another population that has overtly been exposed to this class of compounds is that in
and around Seveso (Italy). In 1976, the Seveso population was exposed to 2,3,7,8 TCDD as a
result of an accidental release from a 2,4,5-trichlorophenol manufacturing plant. The main
route of exposure to the nearby residents was inhalation of and dermal contact with the
contaminated fall-out and ingestion of contaminated food products.
The effects of high levels of exposure can also be studied in the workers employed in,
for example, industries manufacturing PCBs or PCB-containing products. Exposure takes
place mainly via skin absorption or inhalation.
The major route of environmental exposure (more than 90%) is the consumption of
contaminated food from which almost complete absorption takes place.
In the Netherlands, dairy products accounted for half and a mixture of animal and
vegetable oils in e.g. savory snacks, sauces, pastry, and biscuits accounted for a quarter
of the PCB and dioxin Intake.
In other regions, contaminated fish is an important source of exposure.
Low-level exposures to dioxins are also known to interfere with the immune system, the
reproductive system, the endocrine system, and the early growth and development of humans
and animals. In sum, dioxins are a family of powerful all-purpose poisons.
In recent years, the International Agency for Research on Cancer (IARC), a division of
the World Health Organisation, has labelled the most potent dioxin, called TCDD -2,3,7,8
tetrachlordibenzo-p-dioxin, a known human carcinogen. IARC has labelled many of the less
potent dioxins "probable" human carcinogens.
Scientists at the a meeting of 40 scientists convened in Switzerland in May 1998 by the
World Health Organisation concluded that, based on animal experiments, the following
effects might be expected in humans: decreased sperm counts in humans who have a daily
dioxin intake of 14 pg/kg/day; learning disabilities and endometriosis in humans with a
dioxin intake of 21 pg/kg/day; suppression of the immune system might be expected in
offspring of humans with an intake of 37 pg/kg/day. This WHO meeting " recognized
that subtle effects may already occur in the general population in developed countries at
current background levels, 2 to 6 pg/kg body weight. They therefore recommended that every
effort should be made to reduce [dioxin] exposure to the lowest possible level,"
according to a statement released by the World Health Organisation.
They concluded also that dioxin is 2 to 10 times as toxic as it had seemed in 1990, and
a group of German scientists concluded last April that dioxin may be responsible for 12%
of human cancers in industrialised countries. If this estimate were correct, it would mean
dioxin is responsible for 120,000 cancers each year in the U.S. This new German estimate
is at least 10 times as high as previous estimates by U.S. government scientists.
Some dioxins are more toxic than others, and the scientific community has established a
way of comparing the toxicity and the quantities of various mixtures of dioxins. The
technique is called TEQ, or toxic equivalents. The TEQ system takes into account the
variations in toxicity and expresses toxicity in terms of the most toxic dioxin, which is
TCDD.
For example, U.S. EPA estimates that total dioxin emissions in the U.S. averaged about
3000 grams (3 kilograms, or 6.6 pounds) per year TEQ in 1995. This means that all of the
dioxins released into the environment in 1995 in the U.S. had a total toxicity equal to
the toxicity of 3000 grams of TCDD. (EPA acknowledges considerable uncertainty in this
estimate; the true average lies somewhere between 1200 grams and 7900 grams TEQ, EPA says.
The cancer hazard from routine exposure to dioxin has recently been estimated by the
above mentioned group of German scientists. They report that, for adults, the lifetime
cancer hazard lies somewhere between one per hundred and one per thousand for each
picogram of dioxin TEQ ingested per kilogram of body weight per day (pg/kg/day). Since the
daily ingestion in the U.S. ranges from one to 10 pg/kg/day, we can calculate that the
cancer hazard from environmental exposure to dioxin ranges between one per thousand and
100 per thousand. The middle of this range would be 50 per thousand. Because the average
person's lifetime chance of getting cancer is now about 400 per thousand (or four in 10),
we can see that routine exposure to environmental dioxins may be making a substantial
(12%) contribution to the danger of cancer in this country, if the German estimate holds
true. If it holds true, it qualifies as an another public health disaster.
The mechanisms by which dioxin causes cancer, remain poorly understood. In most
studies, dioxin seems to be a powerful promoter of cancer, rather than an initiator. In
other words, once a cell has been made cancer-prone by something else, dioxin may push it
over the edge and turn it into a full-blown cancer. This would explain why dioxin seems to
cause a general increase in many cancers among exposed populations..
In the early 1990s, many governments, including the U.S. government, reported that
everyone in the industrialized world is exposed to substantial quantities of dioxins day
in and day out, thus acknowledging a humiliating failure of the world's public health
apparatus.
